Gareth's publicist had no comment. Katie's publicist has been contacted for comment.

Katie was pregnant with her son Harvey when she had sex with 17-year-old Gareth who strongly denied the fling when it was made public.

The one-night stand led Gareth to quit showbiz for while after his lies were exposed.

Speaking in 2016, Gareth explained: "“I denied the whole Jordan thing because I was 17, I didn't want my family to find out about my sex life. If I hadn't lied it wouldn't have been a big deal, my family, friends and fans wouldn't have felt as let down I guess.”
